The working principle of
diesel generator set that must be started at no-load mainly includes the following aspects:
1. Prevent faults: When the diesel generator set is started, it is first run at no-load to allow the engine components to gradually heat up and avoid mechanical failures or damage caused by sudden loading.
2. Running-in and inspection: No-load operation helps the components to run-in at a lower load, reduce wear and improve overall efficiency. At the same time, no-load operation can check whether the various protection functions of the generator set are normal, such as overload protection, short-circuit protection, etc., to ensure that the unit can be safely shut down in an emergency.
3. Evaluate health status: No-load operation can evaluate the health status of the generator set, find and solve problems in time, and ensure that the unit can provide stable and reliable power support at critical moments.
Specific steps and precautions for no-load start
1. Idle first: When starting, let the engine idle for two or three minutes to allow the components to gradually heat up and reach working condition.
2. Monitoring parameters: During no-load operation, pay close attention to the various parameters of the generator set, such as voltage, current, frequency, temperature, etc., to ensure that they are within the normal range.
3. Recording data: Record the data during no-load operation for subsequent analysis and comparison.
4. Abnormal handling: If an abnormal situation is found, the machine should be stopped immediately for inspection, and the cause should be found and handled.
